so maybe it is unnecessary ? people survived pretty well before formula and routine vit k at birth.
My Mum's cousin died at birth from lack of vitamin k. Not having a go. Obviously most people are fine, but some are not. I'm the last person to play the dead baby card, so I'm not scare mongering. Just factually, it can happen. But then so can many other things. I think do your research and make the best decision you can at the time.
